php实现每天自动变换随机问候语的方法，php变换问候语本文实例讲述了php实现每天自动变换随机问候语的方法。分享给大家供大家参考。具体分析如下：
这里预先定义一个php数组，里面存放一些随机问候语，调用的时候指定是按照天，月还是年来自动更换问候语，如果选择月，则会每月更换一条问候语显示，不用每个月手动更换了，并且这段php代码比使用js实现对搜索引擎友好
function randomquotebyinterval($timebase, $quotesarray){ // make sure it is a integer $timebase = intval($timebase); // how many items are in the array? $itemcount = count($quotesarray); // by using the modulus operator we get a pseudo // random index position that is between zero and the // maximal value (itemcount) $randomindexpos = ($timebase % $itemcount); // now return the random array element return $quotesarray[$randomindexpos];}/*** --> see the example section below for a** detailed instruction.*/
使用范例：
// use the day of the year to get a daily changing// quote changing (z = 0 till 365)$dayoftheyear = date('z');// you could also use:// --> date('m'); // quote changes every month// --> date('h'); // quote changes every hour// --> date('i'); // quote changes every minute// example array with some random quotes$randomquotes = array( 'no animals were harmed in the making of this snippet.', 'nice snippets', 'the modulus operator rocks!', 'php is cool.');print randomquotebyinterval($dayoftheyear, $randomquotes);
希望本文所述对大家的php程序设计有所帮助。
